WIND DIRECTION/COMPASS
The digital compass allows for accurate wind direction measurement . Find the direction of wind by
holding the Xplorer upright facing into the wind . The compass will show the degrees off North, 0 is
North, 90 is East, 180 is South, and 270 is West .
When used for the first time, the compass needs
to be calibrated before any reading is possible.
An initial calibration is necessary, and calibration
when in a new environment will assure the most accurate readings . While in the compass mode, press
and hold the button for two seconds, release when “CAL” is displayed on the top . Slowly turn in a 360
degree circle, about four seconds per quarter turn . When the small circle is complete on the bottom
screen, press the button once to accept .
ALTITUDE & AIR PRESSURE
The SKYWATCH Xplorer 4 has a precise Swiss barometer for measuring altitude and air pressure .
Altitude is measured on the basis of air pressure - this is true in EVERY altimeter, including those found
on aircraft . The Xplorer 4 is designed to perform an adjustment each time it is turned on to adjust to
a close altitude reading . However it is necessary to calibrate to a known altitude before beginning an
ascent or descent . While in an altitude or pressure mode, press and hold the button for FOUR seconds
to change between meters and feet, or hPa and inHg .
Please refer to the instruction manual for detailed
instructions on calibration of air pressure and altitude.
ALTITUDE AND PRESSURE HISTORY
There is one history mode for altitude and two history modes for air pressure . By default the recording
is off; to turn recording of history on, while in any history mode press and hold the button until the
top screen shows anything other than “0h” . To scroll backward through history, from 0h (current)
to 1h, 2h...48h simply press and hold the button. Release the button to stop at a specific time, for
example “6h” will display the measurement from 6 hours before . This is useful for tracking changing
air pressure, or for noting ascent or descent .
